Visioned and Executed by

Honorable Speaker of The National Assembly Mr. Ayaz Sadiq

ABSTRACT

With the increased power demand and energy crisis in Pakistan, it is the need of

hour to shift to alternate energy sources and to conserve the power available.

Energy efficiency audit reports have trimmed us to curtail the power demand of

Parliament Building to 50% while reducing the energy loses, Rest of the

requirement will be met through renewable energy source like photo voltaic solar

power, an environment friendly cradle . It will also be the excellent demonstration

for rest of the country and will also strengthen the Pakistan Building

management standards enactment.

A frequently overlooked feature of the global

energy crisis is the opportunity to save

enormous amount of energy by deploying

energy-efficient technologies. Grasping the

prevailed energy crisis and increasing energy

demands around the nation it was the broad

vision of the Hon’ble Speaker of the National

Assembly, Mr. Ayaz Sadiq to carry out the

Energy Efficiency Audit of the Parliament House,

Islamabad. His principal intention was to

t ransform the Par l iament House into

Greenhouse by reducing all the energy (Thermal

& E l e c t r i c a l ) l o s s e s o f t h e b u i l d i n g .

Green bui ld ing (a lso known as green

construction or sustainable building) refers to a

s t r u c t u re a n d u s i n g p ro c e s s t h a t i s

environmentally responsible and resource-

efficient throughout a building's life-cycle: from

sitting to design, construction, operation,

maintenance, renovation, and demolition. This

requires close cooperation of the design team,

the architects, the engineers, and the client at all

project stages. The Green Building practice

expands and complements the classical

building design concerns of economy, utility,

durability, and comfort. Due to essential use of

e lectr ic i ty in the Parl iament Bui lding,

Islamabad, the sanctioned load of the building

is more than 2.3 MW. Over a period, actual

observed load remains less than 2 MW.

Keeping in view the expenditures of the

electricity bills, the Honorable Speaker of

National Assembly of Pakistan deliberated with

the Federal Minister of Science and Technology

to work on alternate solution in terms of Photo

Voltaic Power generation for Parliament

building. Consequently, Pakistan Council of

Renewable Energy Technologies (PCRET),

Ministry of Science and Technology collected

information for design inputs from the office of

the Honorable Speaker of National Assembly.

PCRET has studied the requirements in detail

and proposed for a National Grid Tied 2 MW

Photo Voltaic Solar Power System for the

Parliament Building. However, Govt. of China

agreed to install 1 MW solar power system in the

parliament house.

With the implementation of the Grid-Tied PV

system we can accomplish the following

objectives:

Solar Electrification of Parliament Building

as substitute of IESCO Electric Supply.

Sizing, Designing, Installation and Operation

of On-Grid Photo Voltaic System capable of

generating 1 MW Electric Power and

connecting to National Grid at 11 kV.

Installation of Net Metering System for this

grid-tied system to claim rebate in electricity

bill of the Parliament Building.

The concept of sustainable development can be

traced to the energy (especially fossil oil) crisis

and the environment pollution concern. The

green building movement originated from the

need and desire for more energy efficient and

environment friendly construction practices.

There are a number of motives for green

building, including environmental, economic,

and social benefits. However, modern sustain

ability initiatives call for an integrated and

synergistic design to both new construction and

in the retrofitting of existing structures. Also

known as sustainable design, this approach

integrates the building life-cycle with each

green practice employed with a design-purpose

to create a synergy among the practices used.

Green building brings together a vast array of

practices, techniques, and skills to reduce and

ultimately eliminate the impacts of buildings on

the environment and human health. It often

emphasizes taking advantage of renewable

resources, e.g., using sunlight through passive

solar, active solar, and photovoltaic equipment,

and using plants and trees through green roofs,

rain gardens, and reduction of rainwater run-

off. Many other techniques are used, such as

using low-impact building materials or using

packed gravel or permeable concrete instead of

conventional concrete or asphalt to enhance

replenishment of ground water.

While the practices or technologies employed in

green building are constantly evolving and may

differ from region to region, fundamental

principles persist from which the method is

derived: Sitting and Structure Design Efficiency,

Energy Efficiency, Water Efficiency, Materials

Efficiency, Indoor Environmental Quality

Enhancement, Operations and Maintenance

Optimization, and Waste and Toxic Reduction.

The essence of green building is an optimization

of one or more of these principles. Also, with the

proper synergistic design, individual green

building technologies may work together to

produce a greater cumulative effect.

On the aesthetic side of green architecture or

sustainable design is the philosophy of

designing a building that is in harmony with the

natural features and resources surrounding the

site. There are several key steps in designing

sustainable buildings: specify 'green' building

materials from local sources, reduce loads,

optimize systems, and generate on-site

renewable energy.

Financial savings of the Parliament building will

be up to Rs. 28 million per annum in terms of

utility bill. The estimated cost of the project is Rs.

280.61 million and the payback period will be

about 10 years.

Social benefits are directly linked to greater

availability of energy generated by 1 MW PV

Solar Power Project of Parliament Building and

electricity which is freed up by the project and

provided to the general economy. Once the

project is completed it will definitely set a trend

for other private and public sector buildings

where huge amount of electric power is being

used to opt the PV Solar Power.

This will also increase the capacity and quality of

local industries in the field of wires, cables and

steel structures. A time will come when other

parts like inverter and isolation transformers

will be produced locally and these industries will

a l so flour ish and consequent ly more

manpower will be required to work in these

sectors. This means more employments

resulting in improved social life of people in the

society.

Solar power facilities reduce the environmental

impacts of combustion used in fossil fuel power

generation, such as impacts from greenhouse

gases and other air pollution emissions. Unlike

fossil fuel power generating facilities, solar

facilities have no emission of air pollutants such

as sulfur dioxide, nitrogen oxides, carbon

monoxide, volatile organic compounds, and the

greenhouse gas carbon dioxide during

operations. In addition to these benefits of solar

development, construction and operation of

solar facilities creates both direct and indirect

employment and additional income in the

regions where the PV Systems are installed and

other solar energy related development occurs.

The solar electrification of the parliament

building will save approximately 2500 tons of

carbon dioxide per annum with a carbon credit

of Rs. 3.445 million per annum if the project gets

registered under CDM mechanism. (1US$ =

Rs.102 and 1 ton carbon abateme)
